[1] Even so good from here that someone may wish to put it in /usr/src/UPDATING but with an additional reference to how to find the most likely llvm since that may change over time... Tested in /usr/src/bin, sbin, usr.sbin, usr.bin... [1] some build but do not install 'no such file or directory' so maybe did not build... Made it into a .sh or .zsh that placed in another location and then run from the location that is being reinstalled, /fsck_ffs/ for example... with the latter as the $1 coded into the script, as the full path on the command line as a parameter. May need improvement... or more coding...
